About Baptiste

PHP/Symfony developer for over 10 years. My goal: clean, maintainable, lasting code.

My experience has allowed me to touch all aspects of the profession: backend development, technical architecture, team leadership, and even the CTO role in a startup.

What motivates me:
→ Structuring code that lasts and is easily maintained
→ Supporting teams in their skill development
→ Modernizing legacy applications (Symfony migrations, refactoring, best practices)

Main stack: PHP 8+, Symfony (4 to 8), Doctrine, REST API, PHPUnit, MySQL/PostgreSQL, Kubernetes

Former CTO and co-founder, I also have a business and product vision that allows me to understand the challenges beyond the code.

Open to discussions about freelance missions in lead dev or Symfony expertise.
